Peningkatan Serapan Hara Nitrogen, Fosfor, dan Kalium Tanaman Sawi Hijau Akibat Konsentrasi Larutan Hara AB Mix pada Media Cocopeat

Abstrak. Larutan Hara AB Mix merupakan pupuk majemuk campuran larut air yang sering digunakan pada sistem media hidroponik. Efektifitas ini sebagai sumber hara bagi tanaman sayur antara lain dipengaruhi oleh konsentrasi pemberian tepat. Percobaan dilakukan di dalam polybag menggunakan rancangan acak lengkap (RAL) terdiri atas 5 perlakuan larutan yaitu: 0,25; 0,50; 0,75; 1,00; dan 1,25 g L-1 dengan empat ulangan. Benih sawi hijau dibibitkan rockwool selama seminggu setelah berumur 20 hari dipindahkan ke ukuran 15×21 cm telah diisi cocopeat. Pemberian setiap bersamaan penyiraman sampai 30 tanam (HST). Sampel daun untuk analisis N,P, K diambil seluruh dipanen umur HST. Daun tersebut sebelum dianalisis, dibersihkan akuades kemudian dimasukkan oven suhu 70 0C. Setelah kering digiling dihaluskan mesin grinder disaring ayakan 0,5 mm. Analisis kandungan N, P, metode destruksi basah. berpengaruh nyata (P0,05) terhadap bobot segar serta dapat meningkatkan serapan K. Konsenrasi optimum diperoleh rentang 1.34 - 1.63 air.Increased Uptake of Nutrients and Green Mustard Due to The Concentration Nutrient Solution in Cocopeat MediaAbstract. is a water-soluble compound fertilizer that often used hydroponic systems. effectiveness the solution as source nutrients for vegetable plants influenced by, among other things, right concentration administration. This experiment was carried out polybags using completely randomized design (CRD) consisting treatment concentrations solution, namely: 0.25; 0.50; 0.75; 1.00; 1.25 water with four replications. mustard seeds were seeded on Rockwool week after days they transferred filled cocopeat media. given every day along watering until old planting (DAT). Leaf samples analysis taken all leaves had been harvested at age DAP. Before being analyzed, cleaned distilled then placed an temperature After drying, it ground mashed machine filtered through 0.5 mm sieve. Analysis nutrient content wet digestion method (Kalra 1998). administration significant effect (P0.05) fresh weight dry greens could increase uptake obtained range water.
